Questions / Answers

Can I expose my skin to the sun after applying the cream?

Retinaldehyde, a benchmark anti-aging active ingredient with clinically proven anti-wrinkle efficacy, is not photostable, meaning that it breaks down upon contact with the sun. To preserve its efficacy, we recommend that you apply YsthéAL creams in the evening. For reinforced anti-aging efficacy, don't forget to apply an SPF50+ sunscreen in the morning, to reduce the impact of UV rays on the skin aging process or, better yet, limit sun exposure to preserve the skin's youthful look for as long as possible.

My skin stings after applying the cream.

Retinaldehyde can cause irritations, redness and tingling on certain skin types, especially sensitive or weakened skin. To prevent these usually fleeting sensations of discomfort, you should allow more time between applications so that the skin can get accustomed to the Retinaldehyde.

What should I do if cream gets into my eyes?

Retinaldehyde is a particularly active molecule, and it should not be applied to the mucus membranes, including the eyes. All contact with eyes should be avoided.
In case of contact with eyes, rinse thoroughly with clean water.

I'm pregnant, can I use YsthéAL creams?

YsthéAL creams have not yet been tested on pregnant women. As a precaution, we do not recommend using these creams during
pregnancy or while breastfeeding.

I have sensitive allergy-prone skin, can I use YsthéAL creams?

YsthéAL products have been formulated to minimize the risks of allergic reactions. They are hypoallergenic.
If you have any doubts, apply a little cream to a small area of the skin. If there's no reaction, you can apply
the cream to your entire face.
